Centriugal casting is the technology and method of njecting liouid metal into the high-speed rotating mold, so that the lioquid metal does centrifugal movement to i the mold and casting the parts. Due to the centrifugal movement, the liquid metal can fiil the mold well in the radial direction and form a free surface of the casting.A cylindrical inner hole can be ootained without a core. Help to eliminate gases and indusions in liquid mietals; It affects the crystallization process of the metal, thereby improving the mechanical and physical properties of the casting.
